Why is my onItemSelectedListener not called in a ListView?

Solution 1:

The OnItemSelectedListener listens for list item selections and not list item clicks.

A selection in this case could be seen as moving the focus on this item with the device's trackpad.

To get the wanted behavior one must use the OnItemClickListener.

Solution 2:

It's because you happen to be testing with your fingers on a touch-enabled device. In touch mode, there is no focus and no selection. UIs that need selection should use a different type of widget, such as radio buttons.

Solution 3:

At first,you should set ChoiceMode,and then,in ListView,there will not accept the selected event because setOnItemSelectedListener registed in AdapterView,and callback in method handleDataChanged(),but class AbsListView override this method and never callback OnItemSelectedListener

you can get the seletedItem by this method in setOnItemClickListener

     mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Log.e("TAG", "onItemClick: " + position);
            SparseBooleanArray positions = mListView.getCheckedItemPositions();
            Log.e("TAG", "onItemSelected: " + positions.toString());

        }
    });
